I do not have access to a lab. I would like to test the growth of mold/bacteria on food items with varying preservatives. (I am testing different processes for preservation.)How can I make a controlled environment for my project so I can do this testing? My goal is to come out with results that would be of ISEF quality. The testing will be done with agar plates, etc.

Thank you so much for helping me. Tell me if you need more information.
